The energy needed to get the water to boiling would be 4180 J
It can be defined as the form of the energy in which heat is transferred from one body to another body due to their molecular movements, thermal energy is also known as heat energy.
As given in the problem You are boiling 100 g of water to make pasta. You start with hot water (90°C). How much energy will be needed to get the water to boiling (100°C)?
water = 4.18 J/g C
the energy needed to get the water to boiling =mCΔT
= 100× 4.18×(100-90)
the energy needed to get the water to boiling =4180 J
Thus, 4180 J energy will be needed to get the water to boiling (100°C)
